Six Flags New Orleans
Six Flags originally Jazzland just off the interstate 10. It was only open 5 years before Hurricane Katrina devastated the sight forcing the new operators to walk away. There have been many mentions of redevelopment, but to this day nothing has come of it. The sight is now patrolled daily by police to keep the urban explorers out and is occasionally used for movies. Slowly over time the swamplands are taking it back. It's last day of operation was August 21, 2005.
